>> i can tell you what it costs in amsterdam. amsterdam is the most expensive place to park your car. it is now 5 euros, nearly $7 per hour, 24 hours per day. also, the question from andy, about 12 years ago, we had a referendum, what to do with the cars in the city. the majority voted for less cars in the city. the last 10 years, the amount of cars went down. it is down 20%, and that was done by making the profiles of the roads a little bit smaller, adding more room for cyclists and public transport, and bringing of the parking fees.
